Prediction Study of Wind Power Generation Power Based on Arima Model

With the rapid development of renewable energy, the share of wind and solar energy in the energy sector is gradually increasing. However, the volatility of their generating power poses challenges to the stable operation of power grids. Wind and solar farms pose new challenges to the stable operation of the grid due to their volatility. The aim of this study is to predict the volatility of wind (wind) power generation using the Arima model so as to enhance the grid's ability to accommodate renewable resources. In this study, historical power generation data from wind farms and solar power plants in a certain region are used, and the triple standard deviation method is applied to deal with outliers, combined with the Lagrangian method to fill in the missing values, and the Arima model is built to make predictions. The results show that the model can better capture the fluctuation trend of power generation. Predictions are made 300 seconds before a significant increase or 120 seconds before a significant decrease in the PV power generation rate value, and the prediction accuracy is obtained by comparing the predicted value with the true value. The predictions show that the model has a high prediction accuracy. The study shows that the Arima model is suitable for short-term prediction of wind power generation, which can provide effective data support for grid scheduling and help to improve the stability and reliability of new energy power generation systems.
